**Halo 4 Spartan Ops: Exodus and the escape from Requiem**

**Halo 4 Spartan Ops: Exodus and the escape from Requiem** **MCC guide. Episode 10 and season-ending spoilers.** The last episode sends you after a replacement power source before you can reach the artifact keeping Infinity trapped. The missions connect closely, but they're still five separate chapters. Keep the current objective in mind when returning through familiar areas: machinery you activated on the way in may be something you need to destroy on the way out. **1. Artifact** Clear the Covenant at the dig site and investigate Glassman's coordinates. The artifact is behind the rock wall, so the next task is recovering the Harvester to drill through it. Its entrance is shielded. Follow the objective toward the anti-aircraft guns and clear their guards while Roland removes their protection. Destroy the guns, return through the reinforcements and let Murphy's Pelican bring down the Harvester's entrance shield. Clear the interior and release the captive scientists using the marked controls. Investigate the damaged power supply, then head for extraction when directed. Rocket ordnance is supplied during the mission, and Covenant fuel-rod weapons provide another heavy option. Use those resources rather than expecting your initial ammunition to last through every Hunter and gun position. At the upper AA position, finish the guarding Hunters before expecting the final shield to drop. If your shots aren't damaging a protected gun, check the current objective rather than continuing to empty ammunition into it. The scientists' rescue explains why the mission doesn't end with the drill firing. You still need a working power source, which is what the next chapters are about. **2. In One Way** Clear the Covenant camp outside the Warrens and try the marked entrance controls. Finish the opposition while Roland gets the door working, then enter the caves. Fight to the Forerunner structure containing the route to Apex. The onward door is locked. Follow the path to the upper levels, cross the light bridges and activate **three control panels** to overload the door's circuits. Clear the remaining Prometheans and return through the now-open passage. This is a good place to separate the navigation problem from the combat problem. The door won't open just because you've killed the enemies standing in front of it. The upper control sequence is required. Before crossing a light bridge, clear the threats you can see at the far end and reload. If you need to back away from a Knight, know where the solid platform begins. An otherwise recoverable fight becomes a death when your retreat takes you off the edge. **3. Seize the Power** Leave the structure, meet Fireteam Forest and advance uphill. Clear the gate area, operate its control and continue to the shielded installation. Destroy the **three generators**, clear the defenders and enter the structure. Defeat the Prometheans and activate the communications console. The alarm summons a Lich. Defeat its deployed forces until it moves into boarding position near the cliff. Use an available jetpack to reach it, fight to the marked engine core and take the core. Leave the ship immediately, then return downhill to the passage back into the Warrens and operate its door control. The core is something you're stealing, not something you're destroying with gunfire. Once it's removed, the ship becomes unstable. Before taking it, notice the route you used to enter so you're not trying to solve that question during the escape. For boarding, wait for the Lich to reach the intended position. Trying to chase it while the ground battle is still active adds risk without completing the required sequence. Check the jump and your jetpack fuel before leaving the cliff. On the return downhill, prioritize getting the core back to the caves. Don't stop in open ground to trade shots with every distant aircraft. **4. Out the Other** Back in the Warrens, clear the nearby Covenant and collect useful supplies from the downed Pelicans. A working Mantis is available among the wreckage. The cave exit becomes shielded. Destroy the **three spherical devices** identified as the power sources for both the shield and the AA guns. These are the devices involved in the earlier passage-opening sequence. Once they're destroyed, move through the exit, defeat the Covenant force outside and clear the landing area for pickup. The Mantis is useful for the heavy fight, but preserve it through the cave rather than driving into the middle of enemies from several directions. Use the machine's range where you have a clear shot and fall back to let its shields recover when you can. The exit opening is only the first half of the job. Outside, the Wraiths and other defenders still have to be dealt with before the Pelican can take you and the core back to the Harvester. **5. One Last Time** Fight back into the Harvester, clear the crew and install the stolen core in the central console. Enter the opened control room and activate the drill. Leave the Harvester and enter the new passage through the rock. Fight through the Knights and Crawlers to the Forerunner structure. When the central door won't open, take the lower route to the power chamber, clear its guards and activate the glowing power device. Return to the upper door, enter the artifact chamber and use its console to deactivate the artifact. Escape back through the caves. Gravity starts behaving unpredictably, so keep your movement controlled instead of committing to unnecessary jumps. Defeat the final Elites near the exit, including the cloaked attackers, then board Murphy's Pelican. Keep a practical close-range weapon for that last fight. The artifact is offline, but there are still enemies between you and the evacuation. If you've emptied a power weapon during the previous room, replace it before rushing into the exit encounter. The power chamber is below the locked door's level; repeatedly trying the upper door won't restore it. Once the power is on, return upstairs rather than searching the lower chamber for the artifact itself. **What to check afterward** Confirm that One Last Time reached its completion screen, then check your chapter records. Finishing the season's final mission doesn't fill gaps in earlier episodes. If an overall difficulty or solo-completion achievement remains locked, compare all fifty chapter entries before replaying random missions.
